Help me pls balance equation

1. 2N₂ + O₂ ---> 2N₂O

2. BaCl₂ + 2NaOH ---> Ba(OH)₂ + 2NaCl

3. H₂SO₄ + 2KOH > K₂SO₄ + 2H₂O

4. K₂CO₃ + 2HCl ---> 2KCl + H₂O + CO₂

5. CaCO₃ + 2HNO₃ ---> Ca(NO₃)₂ + H₂O + CO₂

6. Ca + 2H₂O ---> Ca(OH)₂ + H₂

7. Pb(NO₃)₂ + 2NaI ---> PbI₂ + 2NaNO₃

8. Al₂(SO₄)₃ + 6NaOH ---> 2Al(OH)₃ + 3Na₂SO₄

9. Al(OH)₃ + NaOH ---> NaAlO₂ + 2H₂O

10. 2Pb(NO₃)₂ ---> 2PbO + 4NO₂ + O₂

Explanation:

A balanced equation of a chemical reaction is one that has the number of moles of atoms of each element taking part in the reaction equal on both sides of the reaction, that is on the reactants and products sides of the reaction.

The balanced equations of the given reactions is as follows:

1. 2N₂ + O₂ ---> 2N₂O

2. BaCl₂ + 2NaOH ---> Ba(OH)₂ + 2NaCl

3. H₂SO₄ + 2KOH > K₂SO₄ + 2H₂O

4. K₂CO₃ + 2HCl ---> 2KCl + H₂O + CO₂

5. CaCO₃ + 2HNO₃ ---> Ca(NO₃)₂ + H₂O + CO₂

6. Ca + 2H₂O ---> Ca(OH)₂ + H₂

7. Pb(NO₃)₂ + 2NaI ---> PbI₂ + 2NaNO₃

8. Al₂(SO₄)₃ + 6NaOH ---> 2Al(OH)₃ + 3Na₂SO₄

9. Al(OH)₃ + NaOH ---> NaAlO₂ + 2H₂O

10. 2Pb(NO₃)₂ ---> 2PbO + 4NO₂ + O₂

the answer is the

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
